SPECIFICATION forming part of Letters Patent No. 489,738, dated January10, 1893.

Application filed March 28, 1892. Serial No. 426,885. (No model.)

To all whom it may concern;

Be it known that we, EUGENE G. HAMMOND and EDWARD D. HAMMOND, residentsof the town of Hanover, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in WVashing and SizingMachines, of which the following, in connection with the drawingsaccompanying and forming a part hereof, is a full and completedescription, sufficient to enable those skilled in the art to understandand make the same.

The purpose of our invention is to obtain a device whereby sand, gravel,coal, and other like material can be elevated, water applied thereto, ifdesired, and the material with the water when applied, conveyed to arotatable screen, and such material,and water, if water is used, bedischarged from the screen and the material thereby sized and conveyedto a second screen, where the same operation is repeated until thematerial is separated into the several sizes desired, and where thewater is used as suggested such material in addition to being sized isWashed.

WVe have illustrated our invention by the drawings accompanying andforming a part hereof, in which: 1

Figure 1, is a side elevation of coal, gravel, or sand bins having amachine embodying our invention mounted thereon; Fig. 2, averticallongitudinal section of one of the rotatable screens entering into thedevice with the several spouts in position therewith; showing aconstruction of the perforated cylinder; Fig. 3, an elevation on line3-3 of Fig. 1, viewed in the'direction indicated by the arrows; and Fig.an end elevation of the end of a cylinder embodying certain additionalinventions which may or may not, as desired, enter into the constructionof the device, illustrated in Fig. 1, as embodying our invention.

The same letter of reference is used to indicate a given part where morethan one view thereof is shown in the several figures of the B, is ahopper; and b, is a spout extending therefrom, to and delivering intothe inside of the perforated cylinder D entering into and forming one ofthe elements in. the construction embodying our invention.

D, D D are perforated cylinders constructed and mounted in the samemanner and for the same purposes as is the cylinder D, the onlydifference being in the size of the foraminations or perforations of thecylinder whereby the material passing from the cylinder through suchperforations or foraminations is graded or sized.

E, is a water pipe; and e, is a pump by which water is raised in pipe Eand delivered into the hopper B.

d, d, are the holes or perforations in the several cylinders D, D, D andD Cylinder D as well as the several cylinders D, D D respectively, areillustrated in Figs. 1 and 2 as mounted on the top timbers X of the binsin the hangers F, F, and rotating in such hangers on the shaft G, suchshaft forming the axis of the cylinders respectively, and having thereonarms G extending out to and supporting the foraminated cylinders.

g, is a collar on shaft G holding it in position, that is, receiving thedownward thrust of the revolving cylinder and shaft.

H, is a sprocket wheel on shaft G; and h, is a sprocket chain extendingfrom the sprocket wheel H to and over sprocket wheel h on main drivingshaft H.

I, is a spout extending from under the cylinder D to and delivering itscontents into the cylinder D 5 and I, I respectively, are like spoutsunderneath cylinders D, and D 1 is a spout underneath the cylinder D Theseveral spouts I, I, I I receive therein the material passing from theseveral cylinders, located over them, through the perforations therein,and the material in such cylinders not passing through the perforationsextends the length of the cylinder and passes out of the other endthereof into or on the spouts or hoods J, J, J and J respectively.

WVhere, as in Fig. 1, this machine is placed over bins A, A, the spoutsor hoods J, J, J and J respectively, serve merely to protect the spoutsI, I, I 1 respectively, from receiving the contents of the cylindersdelivered out of the ends thereof and may ibe'a mere hood, but where thematerial delivered from the end of the cylinders is to be conveyed anydistance therefrom a spout is necessary.

As will be readily understood by inspection of Fig. 1, the mannerof'operation of this device is, the material and water is delivered fromthe hopper B through the spout 1) into the cylinder D, the finermaterial therein, cylinder D being continuously rotated, passes throughthe perforations d together with the water, or nearly all of the water,and falls into the spout I, I, while the material not passing throughthe perforations d extends through the cylinder D passing out of thelower end thereof on to the hood J from which it falls into the bin Aunderneath the cylinder D. The liquid and finer material passing intothe spout I, as described, extends along in said spout and is deliveredinto the cylinder D Where it is again sized, the smaller pieces thereofpassing through the perforations 61 in the cylinder D together with theliquid into the spout I being delivered into the next adjacent cylinderin the same manner, while the particles or pieces of the material notpassing through the perforations d in cylinder D extend through thecylin der and out of the end thereof in the same manner as lastdescribed, in regard to the cylinder D, and on to the spout or hood J,falling into the bin A thereunder. As many of the cylinders D, D, D andD are employed as required, the material being delivered as describedfrom one to the next adjacent one.

By this device the liquid employed in Washing the material can be and isretained until the material is completely washed and sized, the mannerof working of the device being to separate the finer from the coarserparticles, to deliver the coarser into its bin or other receptacle, andto carry the finer particles and the liquid to another screen and thererepeat the operation, whereas heretofore the finer particles beingseparated from the machine employed, first, the coarser particles wereseparated farther along in the machine, and thereby the finer particlesalone .Were contained in the Water while the material was being sizedand washed and with such machines the first of the bins A to the leftend of the drawing Fig. 1, would receive the finer particles while, withour device, it receives the coarser particles; the next bin wouldreceive a grade coarser while with us, the same bin receives a gradefiner material, and so on.

In the modification illustrated in Fig. 4-, the shaft G and the arms Gare not used, but in place thereof there is placed on the cylinder Dring K having thereon gear teeth 70, 7c, intermeshing with the teeth ona driving gear K. And the cylinder D rests on the revoluble pulleys orwheels L, L, such pulleys L turning on shafts 1,1, respectively. As thecylinder D is precisely the same as the several cylinders D, D, D Dinclusive, except the shaft G and spokes G, being removed from withinthe cylinder, material of larger size in proportion to the size of thecylinder can be passed through the same.

It is to be understood that the several cylinders vary only in the sizeof the perforations and that the letterings D,D, D ,D D, have been giventhereto, to avoid confusion in the describing of the device.

The several spouts b, I, I, I and I and the spouts or hoods J, J, J Jrespectively, form conveyers in which the material received thereon, isconveyed to the point of delivery thereof hereinbefore set out, and wedo not confine ourselves to the precise shape of such conveyers, or tothe exact location thereof as regards distance from the severalcylinders, or to the size thereof it being, however, necesary that theconveyor 1) deliver it contents into the first of the cylinders, thatthe series of conveyers I, I l and I extend, respectively,longitudinally underneath the several cylinders sufficiently near and ofsufficient size to collect all the material coming through theforaminations in the cylinders, and that each of such conveyers mustextend to and deliver the contents thereof as hereinbefore stated; andthat the conveyers formed by the hoods or spouts J, J, J J respectively,must fully protect the spouts I, I, I 1 from receiving any of thematerial passing out of the ends of the several cylinders, and Wheresuch conveyers-J, J, J J are designed to carry the material deliveredinto them a distance, that they be of sufficient size, proper shape andsuitable construction to receive such material and convey the same asdesired.

Having thus described our invention, What We claim as new and desire tosecure by Letters Patent is:

In a washing and sizing machine, a main driving shaft having sprocketwheels thereon, a series of rotatable foraminated cylinders all drivenfrom said main shaft by chains passing over the sprocket wheels thereon,a pump driven by a chain passing over a sprocket wheel on said mainshaft, and a hopper, into which said pump discharges, for feedingmaterial to said cylinders, substantially as described.
